Simple Lisp Interface Kit (SLIK)

SLIK is a library of lightweight user interface widgets and
components, written in Common Lisp. It uses the X window system
through CLX, and includes dispatch and event handling. The source
code is available here as a gzipped tar
file, version 2.2. A programmer's
reference manual (PDF) is also available.
